It might be easy to brush off my complaint as a case of paleo-pedantry, but word choice matters. “Dinosaur” is a word for a specific group of creatures united by shared characteristics and which had their own evolutionary history—it is not a catch-all term for anything reptilian and prehistoric.
We have known about this distinction for a long time, and I bet that your average 10-year old paleo fan would know not confuse the groups.
Low IQ: crosc looks like dinos so they are the cloests living relative to dinos.
Mid IQ: birds are direct descendents of dinos so they are the closest living relatives to dinos.
High IQ: since birds are direct descendent they are just dinos, not a relative. Which makes crocs the next closest living relative to dinos/birds.
The joke is that birds aren’t only related to dinos, but are dinos themselves.
Yes and the cruel part is… Pterosaurs are not Dinosaurs!

So, it’s a joke about the fact that both are essentially dinosaurs?
… nope, I got nothing …
Here’s my take:
Low IQ: crosc looks like dinos so they are the cloests living relative to dinos. Mid IQ: birds are direct descendents of dinos so they are the closest living relatives to dinos. High IQ: since birds are direct descendent they are just dinos, not a relative. Which makes crocs the next closest living relative to dinos/birds.
